snowpeak ruins - how to get heart containers

just finished this level
how ever theres 2 chests left so i assume they are they heart containers
theres on on 2F i know on the swinging platforms
i cbf getting that one coz its hard
but the one thats on 1F, how do i get across the giant gap?

Use the metal ball to whack the platforms. That will get them moving. Hit them at the right angle. To get the chest that has that gap in the F1 floor, go to F2 with the ice beasts in cages. Climb up to the top and look at the red carpet. Use the ball and chain here as well. Drop down and claim your prize.
